The CS424 is a high-quality 2-way ceiling speaker consisting of a 4” woofer and a coaxially mounted 1” tweeter. The high-quality components in combination with the steel back can provide premium performance for background music as well as paging systems, no matter what kind of ceiling or surface the speaker is mounted to. The power of 30 Watt, wide frequency response and low distortion makes the speaker perfectly suited for applications requiring a higher fidelity of music such as restaurants, retail stores, professional offices and many other applications. The integrated 100 Volt line transformer makes the speaker suitable for use in large 100 Volt Public Address systems. The power can be selected in three steps of impedance for 100 Volt applications and an 8 Ohm tapping for low impedance applications using the rotary switch behind the front grill. The connection of the speaker can be done using the 4-pin Terminal block connector at the rear side of the back can, allowing parallel linkthrough to other speakers. Installing the speaker can be accomplished in seconds, without requiring access above the ceiling, using the simple quick-fixing mechanism.
